It is shown that in a class of models of the quantum field theory the perturbation expansion of the resolvent operator, (H - z)-1, converges for all complex z. The class of models consists of all theories with Yukawa coupling in which the vacuum polarization was neglected. Finally, the method used was that of comparison with the exactly solvable neutral scalar model.
